1 Claim. 1

This invention relates to book marks, and more particularly to that typeof book mark which is permanently secured to the cover of the book withwhich it is used.

An important object of the invention is to provide a book mark of thischaracter wherein a yieldable arm, forming a part thereof, and which isnormally held between pages of the book, will automatically move to itsproper marking position between leaves of the book, as the leaves areturned in reading.

Another important object of the invention is to provide a device of thischaracter which when properly positioned on the cover of the book, willbe maintained in its operative position at all times, and will notbecome displaced to defeat the operation of the device and purpose oftheinvention.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is an elevational view of a book mark, constructed inaccordance with the invention.

Figure 2 is a sectional view taken on line 2-2 of Fig. 1.

Y Figure 3 is a sectional view taken on line 3- 3 of Fig. 1.

Figure 4 is a detail view illustrating the manner of securing the springarm in position on the main portion of the book mark.

Figure 5 is a perspective view illustrating the application of the bookmark.

Figure 6 is a sectional view taken on line 6-5 of Figure 4.

Figure 7 is a longitudinal sectional view through the end of the mainsection showing a modified form of wire structure at its point ofconnection with the main section.

Referring to the drawing in detail, the book mark comprises a mainsection 5 which includes a length of sheet metal material having asection 6 thereof bent inwardly along one longitudinal edge of the mainportion, the inwardly bent portion 6 being disposed in spaced relationwith the main portion as clearly shown by Fig. 3 of the drawing.

This section 6 is of a width so that its free longitudinal edge, will bespaced from the free 2 longitudinal edge of the main section 5, as shownby Fig. 1, to permit the device to be guided and readily positioned overone edgeof the cover of the book, which in the present showing is inthemain portion 5, which is gripped thereby to secure the, marker arm inposition.

This inwardly extended end I 0 of the main portion, provides a shoulderand stop, adapted to engage one edge of the cover of the book, toprevent the main portion from being slid too far, towards the center ofthe book, to render the arm inoperative to accomplish its purpose.

The arm l is of a length to extend an appreciable distance beyond theinner end of the main portion 5, the free end of the arm I beingextended downwardly at an oblique angle with respect to the main portionof the arm, where it will move between pages of the book, providing amarker.

It might be further stated that depressions are provided in the outersurface of the portion 6, defining enlargements ll, adapted to cause thesection 6 to grip the book cover with which the book mark is used.

Due to the construction of this arm, and because of the material fromwhich the arm is made, the arm will move upwardly and snap behind a leafwhich has been turned. Further, the operation of the book mark isentirely automatic, and when one completes the reading of a page, andcloses the book, the mark will automatically assume its position to marka certain page of the book.

In the modified form of the invention as shown by Figure 7 of thedrawing, the wire 9 is bent into substantially U-shaped formation. Thisform of wire may be used in lieu of the illustration shown by Figure 6.

From the foregoing, it is believed that the construction and operationof the book mark will be obvious, and that a further disclosure as tothe operation and use of the marker is unnecessary.

What is claimed is:

A book marker including a clamp, substantially U-shaped in crosssection, formed from a fiat piece of sheet material bent longitudinallyupon itself to provide outer and inner clamp sections adapted to engagebetween them a book cover, the bend connecting said sections straddlingthe upper edge of the cover, a relatively elongated tubular shoulder,non-circular in cross section, on the clamp, an end edge of one of theclamp sections being rolled to provide said shoulder, said shoulderbeing disposed wholly beyond and adapted to fit against the side edge ofthe 4 extended from the shoulder at a right angle thereto vand outsideof and in parallel relation to the bend of the clamp, and said medialportion terminating in a free end inwardly extended to lie againstleaves of the book and to move therebetween when said leaves are turned.
